The online car auctioneer charges a commission for classified ads. if the car sells the seller is charged 4% of the advertised price not of the price for which the car actually sells. if the car doesn’t sell the seller pays nothing. if barbara advertises her cadillac for 13000 and sells it for 12800 how much must she pay for the ad

First one is 1 second one is 3

In all honesty, there really is no “work” per say to show. mainly it’s just using the process of elimination. the question is asking which domain(s) would be the most appropriate for the function c(n). n is the number of observed vehicles so right away, 1, 2, and 3 can be eliminated.why? 1, 2 start in the negatives and therefore it is impossible to observe negative cars. so, #4 would be the best answer to the given problem.
